How Long do we have to bring milk tin to the childcare? All the way to k2?

Milk powder stopped but they still serve warm milk in school for breakfast. However I'm still providing my own brand of milk as my son is unable to take the school's milk.

Mine stopped at N2. The teachers told us to stop bringing milk as they were trying to transit my son and the other kids to have their naps without milk.

My Son in N1 now. Last week stopped bringing milk to sch as sch will be training him

Mine stopped when my daughter was in playgroup. About 3yo

They stopped the milk powder at K1. they offer UHT milk
